Field of the Invention The present invention relates to a heat resistant hose and a method of manufacturing the same, and to a heat resistant hose and a method of manufacturing the same, having a durability to withstand high temperatures of a silicone hose used in automobiles.

일반적으로 고온용 공기를 전달하는데 사용하는 호스는 여러 가지 종류가 있는데, 특히 고온용 공기의 특징상 여러 가지 조건이 요구된다.In general, there are many types of hoses used to transfer hot air, and in particular, various conditions are required due to the characteristics of the hot air.

예컨대, 자동차 엔진의 배기 매뉴폴더에는 800도 이상의 고온의 연료 및 공기가 통과하게 되며, 이러한 배기 매뉴폴더를 연결하는 실리콘 호스가 고온을 견딜 수 있도록 내구성을 지녀야 한다.For example, the exhaust manifold of an automobile engine passes high temperature fuel and air of 800 degrees or more, and the silicone hose connecting the exhaust manifold must be durable to withstand high temperatures.

이를 위해 방화처리 등의 특수 공정이 필요하게 되는데, 종래에는 실리콘 호스의 외면에 석면을 부착하여 내열성을 가지도록 하였다.To this end, a special process such as fire protection is required. In the related art, asbestos is attached to an outer surface of a silicone hose to have heat resistance.

그러나, 이러한 석면 재질은 인체에 큰 유해성을 가져오며, 또한 수명이 짧아서 잦은 교체가 이루어져야 하는 문제점이 있다. However, these asbestos materials bring great harm to the human body, and also have a problem in that frequent replacement is required due to short lifespan.

이에 본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위하여, 실리콘 호스의 외면 알루미늄 박막을 부착하여 내열성 및 친환경성을 가지도록 함과 아울러 수명을 연장시키도록 한 내열 호스 및 그 제조 방법을 제공하는데 목적이 있다.In order to solve the above problems, the present invention provides a heat resistant hose and a method of manufacturing the same by attaching an outer thin aluminum film of a silicon hose to have heat resistance and eco-friendliness, and to prolong life. There is a purpose.

이러한 목적을 달성하기 위한 본 발명의 내열 호스는,Heat-resistant hose of the present invention for achieving this object,

자동차의 배관에 사용되는 실리콘 호스의 외면에 섬유층, 실리콘층, 알루미늄 박막층이 순차적으로 형성된 단열 기재를 부착하여 구성된다.It is comprised by attaching the heat insulation base material in which the fiber layer, the silicon layer, and the aluminum thin film layer were formed in order on the outer surface of the silicone hose used for piping of an automobile.

또한, 이러한 내열 호스를 제조하기 위한 방법으로는,Moreover, as a method for manufacturing such a heat resistant hose,

섬유의 상부에 실리콘을 위치시킨 다음 롤링하여 결합하는 제 1 과정;Placing a silicon on top of the fiber and then rolling and bonding the silicon;

상기 제 1 과정에 의하여 롤링된 실리콘의 상부에 알루미늄 박막을 위치시킨 다음 재롤링하여 히트 실드(Heat Shield) 원단을 형성하는 제 2 과정;Placing a thin aluminum film on top of the rolled silicon by the first process and then rerolling to form a heat shield fabric;

상기 제 2 과정에 의하여 형성된 히트 실드 원단을 실리콘 호스의 표면에 위치시킨 다음 코팅 용제에 의하여 부착하는 제 3 과정;으로 수행된다.And a third process of placing the heat shield fabric formed by the second process on the surface of the silicon hose and then attaching the heat shield fabric by the coating solvent.

이하 본 발명을 첨부한 예시도면을 참조하여 자세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 1 은 본 발명에 따른 내열 호스의 제조 공정을 도시한 도이고, 도 2 는 도 1에 의하여 제조된 내열 호스의 외관을 보인 도이다.1 is a view showing a manufacturing process of the heat resistant hose according to the present invention, Figure 2 is a view showing the appearance of the heat resistant hose manufactured by FIG.

먼저 도 1의 (a) 에 도시된 바와 같이 섬유(100)의 상부에 실리콘(200)을 위치시키게 되는데, 이러한 실리콘(200)은 도면에서 판 형태로 도시되었지만 스프레이 등에 의하여 섬유(100)의 상부에 도포된다. First, as shown in (a) of FIG. 1, the silicon 200 is positioned on the top of the fiber 100. The silicon 200 is shown in the form of a plate in the drawing, but the top of the fiber 100 is sprayed or the like. Is applied to.

물론, 판 형태로 된 실리콘재가 섬유(100)의 상부에 위치하는 것도 무방하다.Of course, the silicon material in the form of a plate may be located above the fiber 100.

이렇게 섬유(100)와 실리콘(200)이 준비되면, 이를 롤링하여 결합시키게 되는데, (b)에 도시한 바와 같이 섬유(100)가 내측에 위치하고 실리콘(200)이 외측에 위치하도록 롤링을 하게 된다.When the fiber 100 and the silicon 200 are prepared in this way, they are rolled and combined, as shown in (b), so that the fiber 100 is located inside and the silicon 200 is rolled outward. .

이때 롤링을 위해서는 금속으로 된 봉의 외측에 섬유(100)가 부가된 실리콘(200)을 감싸서 롤링을 행하게 되고, 그 롤링된 섬유(100) 및 실리콘(200)의 단부 끼리는 서로 접착시키지 않음으로써 개방부위(300)가 발생된다.At this time, the rolling is performed by wrapping the silicon 200 to which the fiber 100 is added to the outer side of the rod made of metal, and the rolled fiber 100 and the ends of the silicon 200 do not adhere to each other to open the site. 300 is generated.

또한, 상기 섬유(100)와 실리콘(200)은 롤링 시에 서로 압착이 이루어져서 섬유(100)에 의해 실리콘(200)의 파열강도가 증대되는 것이다.In addition, the fiber 100 and the silicon 200 are compressed to each other when rolling, thereby increasing the burst strength of the silicon 200 by the fiber 100.

상기 롤링되어 결합된 실리콘(200)의 표면에 단열 부재가 부착되는데, 이러한 단열부재는 알루미늄이 박막 형태로 구성됨이 바람직하다.The heat insulating member is attached to the surface of the rolled and bonded silicon 200, and the heat insulating member is preferably made of aluminum in a thin film form.

도 1의 (c)에 도시한 바와 같이 알루미늄 박막(400)을 롤링이 이루어진 실리콘(200)의 표면에 위치시킨 다음 금속 봉에 의하여 재차 롤링하여 압착시킴으로써 이들을 결합하여 히트 실드(Heat Shield) 원단을 만들게 된다.As shown in (c) of FIG. 1, the aluminum thin film 400 is placed on the surface of the rolled silicon 200, and then rolled and pressed again by a metal rod to combine them to form a heat shield fabric. Will be made.

결국, 내측에 섬유(100)가 위치하고, 그 섬유(100)의 외측에 실리콘(200)이 위치하며, 그 실리콘(200)의 표면에 알루미늄 박막(400)이 입혀짐으로써 단열 기재(1)가 형성되어 지는 것이다.As a result, the fiber 100 is located on the inner side, the silicon 200 is located on the outer side of the fiber 100, and the heat-insulating substrate 1 is coated by coating the aluminum thin film 400 on the surface of the silicon 200. It is formed.

이렇게 형성된 단열 기재(1)는 도 1의 (d)에 도시한 바와 같이 실리콘 호스(500)의 외측에 씌워지게 되는데, 이는 상기 개방 부위(300)를 통해 단열 기재(1)의 내측으로 실리콘 호스(500)를 끼워 삽입함으로써 실리콘 호스(500)의 외측에 단열 기재(1)가 위치하게 되는 것이다.The heat insulating substrate 1 thus formed is covered with the outside of the silicone hose 500 as shown in (d) of FIG. 1, which is a silicone hose inside the heat insulating substrate 1 through the opening portion 300. By inserting the 500, the heat insulation base material 1 is located in the outer side of the silicone hose 500. FIG.

이때, 상기 실리콘 호스(500)와 단열 기재(1)의 내측에는 코팅 용제를 미리 도포함으로써 그 코팅 용제에 의하여 이들이 서로 부착되도록 한다.At this time, by coating the coating solvent in the inside of the silicone hose 500 and the heat insulating substrate 1 in advance so that they are attached to each other by the coating solvent.

상기의 코팅 용제는 열에 강하면서도 부착성이 뛰어난 용제가 되어야 하며, 대표적으로 나프타(Naphtha) 또는 자일린(Xylene)이 될 수 있다.The coating solvent should be a solvent resistant to heat and excellent in adhesion, and may be representatively naphtha or xylene.

이로써 도 2 에 도시한 바와 같이 상기의 실리콘 호스(500)의 외측에 단열 기재(1)가 부착되어 지며, 이러한 단열 기재(1)는 실리콘 호스(500)의 모든 부위에 부착될 수도 있으나, 경제성을 고려하여 고온과 접촉하는 부위 예를 들면, 엔진의 주위, 배기 매뉴폴더와 닿는 부위 등에 국한적으로 부착될 수 있을 것이다. As a result, as shown in FIG. 2, the heat insulating substrate 1 is attached to the outside of the silicone hose 500, and the heat insulating substrate 1 may be attached to all parts of the silicon hose 500, but it is economical. In consideration of the high temperature, it may be attached to, for example, the area around the engine, the area in contact with the exhaust manifold, and the like.

결국, 열에 약한 실리콘 호스(500)의 외면에 단열 기재(1)를 부가함으로써 실리콘 호스(500)가 내열성을 갖도록 한 것이다.As a result, the heat-insulating substrate 1 is added to the outer surface of the heat resistant silicone hose 500 so that the silicone hose 500 has heat resistance.

이상에서 설명한 바와 같이, 본 발명에 따른 내열 호스 및 그 제조 방법은 실리콘 호스의 외면에 알루미늄 박막을 부착하여 내열성 및 친환경성을 가지도록 함과 아울러 수명을 연장시키도록 한 효과가 있다.As described above, the heat resistant hose and the method of manufacturing the same according to the present invention have an effect of prolonging the life and having heat resistance and eco-friendliness by attaching an aluminum thin film to the outer surface of the silicon hose.
